Spider Robot: A spider-shaped robot is being developed in Sydney that can build a full-size house in just one day. The name of this robot is Charlotte and the developers claim that it can erect strong walls of a house up to 2,150 square feet in a completely autonomous manner. The special thing is that it neither requires transportation of cement nor bricks, this robot makes layer-by-layer walls by pressing soil, sand and clean waste on the site itself.

Charlotte – the next generation construction robot

According to Earth.com, Charlotte is a mobile, legged system that combines 3D printing and additive manufacturing. Its design shows the direction in which the future construction sector is moving. Crest Robotics Director Clyde Webster’s team developed it specifically for construction jobs that are heavy, repetitive or risky.

According to Dr. Jan Golembiewski of Earthbuilt Technology, even something as simple as a brick goes through many carbon-intensive processes. In such a situation, systems like Charlotte can reduce carbon emissions to a huge extent.

New technology of construction from soil to house

Crest’s technology uses a special undercarriage system to collect soil, sand and crushed waste and press it into layers with textile binding. This technology is based on extrusion i.e. walls are formed by expelling material from a nozzle in continuous layers. The team says that this robot can work at the speed of 100 workers. Because of its legs it can move easily even on rough ground where wheeled machines get stuck.

Carbon emissions and costs will reduce

The construction sector would contribute 37% of carbon emissions in 2022. In such a situation, Charlotte’s cement-free method can significantly reduce the carbon footprint. It also reduces costs by converting clean waste into strong walls. Repetitive and risky tasks will be handled by robots, which will also reduce the risk of injury to human labour.
